Description
| - Cílem práce bylo stanovení vlivu aplikace 17α?methyltestosteronu na vývoj testikulárníchch buněk u novosamců kapra obecného (Cyprinus carpio L.) ve srovnání s diploidními samci. Gynogenetický plůdek kapra obecného (průměrná hmotnost, BW, 2.6?0.3 g; průměrná celková délka, 10.4?0.5 cm) byl krmen po dobu 40 dnů 17 α -methyltestosteronem (MT) v dávce 100 mg kg1. Krmení plůdku MT vedlo k indukci zvratu pohlaví v rozmezí od 61.5 do 100%. Novosamci vykazovali signifikantně nižší (P < 0.05) tělesnou hmotnost (BW 22.9?0.8) ale signifikantně (P < 0.05) vyšší průměrnou hmotnost gonád (2.1?0.3) a vyšší gonadosomatický index (GSI 9.5?0.2%) ve srovnání s kontrolní skupinou (BW 54.8?1.3; GSI 0.61%). Navíc orální aplikace MT mněla za následek zvýšený počet samců z abnormálním vývojem gonád. Orální aplikace MT také vedla k průkazně vyššímu objemu germinálnych buněk, objemu jádra a objemu cyst (P < 0.01 ve všech případech) ve srovnání s kontrolní skupinou. Celkový počet Sertoliho buněk v cystě vzr (cs)
- The main objective of the present study was to investigate the effects of 17 α -methyltestosterone treatment upon the testicular germ cells of gynogenetic masculinized neomale common carp (Cyprinus carpio L.) in comparison with diploid carp. Gynogenetic common carp progeny (mean body weight, BW, 2.6?0.3 g; mean total length, 10.4?0.5 cm) were treated for a period of 40 days with 17a-methyltestosterone (MT) at a dose of 100 mg kg1. The oral administration of MT resulted in 61.5 - 100% of fish exhibiting male gonads. The masculinized neomales exhibited reduced (P < 0.05) body weight (BW 22.9?0.8) but significantly increased (P < 0.05) mean testis weight (2.1?0.3) and mean gonadosomatic index (GSI 9.5?0.2%) in comparison with fish not treated with MT (BW 54.8?1.3; GSI 0.61%). Furthermore, treatment with MT also resulted in an increased number of fish exhibiting abnormal gonads. However, neomales did not exhibit abnormalities in the development of sperm ducts. MT treatment significantly increa
